A mathematical model based on enzyme kinetics shows how the relationships between life expectancy, survival rates for children and adults, and national income change over time.

A combination of detailed sampling and mathematical modeling suggests that the response of immune cells to reactivation of herpes simplex virus 2 is extremely rapid and effective within microscopic areas of genital skin.

The Botryllus schlosseri genome yields insights into the evolution of hematopoiesis.

A chemical screen reveals that a compound used to treat a parasitic disease can trigger pluripotent stem cells to become neurons, uncovering a novel mechanism behind neuronal development.

One-quarter of the Chondrichthyes have an elevated risk of extinction, mainly as a result of overfishing.

In the Arabidopsis epidermis, the internal mechanical stress of a cell competes with the external stress to control microtubule behavior, providing a framework to understand the mechanical feedbacks that underlie plant morphogenesis.

Malaria 'hotspots' can be identified that range in size from a few homesteads to a village, and it will be necessary to eliminate hotspots at varying scales as we progress towards eliminating malaria.

Zebrin-positive cerebellar Purkinje cells fire at lower frequencies than zebrin-negative cells, indicating that cerebellar circuits are not physiologically homogeneous.

Understanding where future Ebola virus outbreaks may start and the changing nature of the populations living in these places is of critical importance in helping to prepare for future outbreaks.

The West Nile Virus envelope protein catalyzes membrane fusion through low-pH induced conformational rearrangement, with a rate determined by the formation of two trimeric complexes at the contact zone between the virus and target membrane.
